Paper Abstract

A set of 200 Tessar lenses, covering a wide range of f/ numbers and angular fields, was designed with a consistent optimization scheme. Four different high-index crown glasses were used for the front and back elements, while the glasses of the remaining two elements were optimization variables. The imaging quality and trends in the index and dispersion of the variable glasses were analyzed and described.
